Hi

we are in fact working on this type of properties.
However, it might still take some time before it is ready to use.

regards

Hi Daria,

as far as I know, there is currently no work going on in this direction. The problem is that there is currently nobody working on LR properties, i.e. there won't be analytical polarizabilities in the near future and thus no straightforward Raman spectra.
Nevertheless, there is the possibility of computing the Ranman spectra numerically as CP2K provides the option of a periodic electric field. Using this option you could get polarizabilities by numerical differentiation and from there compute the Raman intensities of the normal mode of interest.

Cheers
Flo
